To a/ZZ whom it may concern:

Be it known that I, RICHARD P. WILLIAMS,

'o f thefborough ofBrooklyn, city of New where y the tongue is securely held down to its seat on thev bed of. the structure and is thereby prevented from kicking or accidental throwing; also, to provide a construction in which the tongue can b'e readily and quickly removed when necessary to repair and re- 'newitjv With these objects inview my invention consists in the lnovel construction and combination of parts, 'all substantially as hereinaf-4 l ter described, and pointed out in theappended mg drawing-in whichl Figure 1 is a plan view of a tongue-switch embodyingmy invention; Fig. 2, a partial longitudinal section taken on the line 2 2 of claims, reference being had to theaccoI-npany- Fig.v 1; Fig. 3,-a. lan view of the switchtongue removed; ig. 4, a transverse section on the line 4 4 of Fig. 1, and Fig. 5 a detail vvided at ashes-wit 4o view of the locking-plate.

The letter A desi ates the body ortion of i the structure, while is-,formed wit a seat a for the movable ton e Saidjtongue is proila depending cylindrical projection b, whichtermmates at its lower end in a circular enlargement or flange b.

The portions b and b may be formed integrally with the tongue B, or theymay be secured thereto. To receive the convex heel end of the tongue and the ortion b, the body structure is formed with the convexbearin seat c, and to receive the flan e portion b it 1s formed With the undercut caring c.` To permit the tongue to be seated, the bed a is recessed, as shown at a.

D is a locking and bearing member or plate which is inserted in the recess a after the tongue is seated with its concave edge d in bearing engagement With the portions b`b.

It is Ithen secured in place by'means of the keys or wed es E driven behind it. F designates a harfgl ably .seated underneat of the tongue, but which ma be omitted.

In the mannerv described I form a secure and eiicient bearin 'for the ton obviates Vthe use of t employed. The plate E, in connection wit e which'l e long heel-pin usuallyl ssl bearinglate, which is preferthe fiange portiomb the undercut-.bearingc,also forms secureV means-for holding the tongue down toits seat to preventits kicking2 and accidentalthrowf ing. The tongue can be readily-removed at' any time by loosening the keys orV wedges F and removing the plate D, which can be done i without. disturbing the balance of the structure in its position in the track. Toffacilitate the removal ofthe plate D, the recess dfmay be provided. The ywear in thev bearing may also -be taken up at any time by. drivinggthe keys or wedges or, by removin them and redrlvingv them 'against shimsor iners. I do not wishv to limit myself to the'precise construction which I have herein shown and described, asl various changes may be made -in the details thereof without departing from the spirit and scope of my invention. Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, isf j 1. In a tongue-switch, the combination With a switch-tongue having a de ending bearing member at 1ts heel portion, o a locking member arranged to engage and disengage witha switchtongue having-a depending iianged'bearing) member, of a locking-plate engaging said caring member, and means forremovably securing the lockingf late. 3. In a tongue-switch, the com inationl with the bodyportion ofthe structure hav- 1n svtc'h-tongue, of a tongue ha alockingplate engaging said fla ed member. 4. In a tongue-switc the combination with the bod portionhavin the undercut bearing at its eel portion, of t e tongue having the depending flanged bearing memberv said bearing, the removable 'lockw ch secure said locking-plate.

the' bearing member by horizontal 'move- 'I an undercut bearing for the end of a i a fianged v and the removable keys'or wedgesv 5. Ina tongue-switch, the combination -With'the body ortion of the structure having a bed or seat or a tongue, said bed being recessed and undercut at its heel portion and a hard bearingfplate seated in said recess,'of` a tongue having a depending fianged bearing member enfgaging the undercut ofthe body portion an bearing on said plate and aremovable locking member seated in said recess and engaging said bearing member.

6. In a tongue-switch, a switch-tongue having at its heel a depending projection, terminating at its lower end in a circular horizontal flange oflarger diameter than the body portion of the projection.

7. n a tongue-switch',` the combination --With a switch-tongue having a depending pin at -its-heelend, of a holding and bearing-member for the .front portion of the pin, arranged to move horizontally toward and away from the same, together with means for securing .said member.

8. .In a tongue-switch, the combination with a switch-tongue having a-depending pin at its heel end, of a holding and bearing member for the front portion of the pin, arranged to move horizontally toward and away from the same, and a wedge for securi and adjustinlglthe said bearing member.

a tongue-switch, the' combination with a body portion having an undercut portion at `the heel, of a tongue having a'. large tally-movablebearing-piece 1n front of said pin, means for securing the same in engagement With the pin, and a hard-metal bearingpiece for the lower end of the said pin.

11. In a tongue-switch, the combination with an undercut body portion, of a tongue having a large bearing-pin extending under the said undercut body portion, a hard-metal bearing-plate for the lower end of said pin, and a removable locking and bearing member arranged to engage and disengage the front portion of said pin by horizontal movemeut, together with wedge devices for holda Vrear bearing ing and adjusting said' locking and bearing. 4
